IMPROVEMENT IN INKING APPARATUS FOR COLOR-PRINTING.

Specification forming part of Letters Patent No. 130,82Q, dated August 27, 1872.

Specification describing certain Improvements in Inking Apparatus for Color-Printing, invented by ISRAELL. G. Bron, of Cambridge, county of Middlesex, State of Massachusetts.

My invention relates to sectional ink-fountains of improved shape and construction, by means of which good distribution is easily obtained.

Figure 1 is a plan view of a machine embodying my invention, Fig. 2 is a side elevation of the same. Fig. 3 is a section through the line A B. y

a a are sectional fountains. b b are screws to depress the spring-scraper or fountain-knives c c, which removes the superfluous ink from the fountain-rollers d d. 6 is a roller that conveys the ink from the fountain-rollers to the sectional distributors i 73; a reciprocating n10- tion is given this roller by means of the cam m and lever 0. The fountain-rollers in the fountains are placed on the shaft 1, the opposite end of the fountain resting upon the slotted frame r. This frame has a slot, q, and through it setscrews 3 s are placed to secure the fountains in their respective situations. The shaft l is turned by a ratchet upon it, operated by the arm 9 and cam n. The ink, being conveyed by the roller 0 from the fountains to the sectional rollers t' i, is distributed upon them by the vibratin g rollers g g, operated by the cam 70. The sectional rollers Mare placed upon the shaft 2 at points corresponding with the form df type, sectional rollers being used of the same width as the line of type to be put in any particular color; to separate them divis' ional collars w a; are used, and, finally they are secured upon the shaft by the nuts to w. h h are screws to adjust the distributers g g.

This inking apparatus is particularly de signed for the cylinder-presses now generally used throughout the country. The inking-rollers that apply the ink to the type being directly below the sectional rollers t i, are of course in contact with it. Practically this combination is found to work in such a manner that good work is obtained, and, with reasonable care, there is no admixture of the different colors.

I do not claim as new the use of sectional fountains, they having been invented at least thirty years ago; neither do I claim vibrating rollers for distributing ink; but

What I do claim, and desire to secure by Letters Patent, is

The combination of the shaft 2 with the sectional collars .r w, and rollers '5 i with the distributing rollers g g, and the reciprocating roller 0, fountain-rollers d d, and the fountains a a, substantially in the manner and for the purpose set forth and described.
